ui: Added tabs UI to top of main window (issue #215)
* Added tab bar to top of main window with UI/shortcuts similar to web browsers * ComponentManager offers components for 2 use-cases: application and tab * Application components: log view (status/errors), bookmarks, screen search, status bar, tabs, tooltips, dialogs and all tab views disabled * Tab components: graph, code, history and search * When a project is loaded there is always at least one tab, otherwise there is none * Each tab replaces the application views of the same name in the main layout when activated * Each tab has it's own TaskScheduler, to process tasks independent from other tabs * The application has a global TaskScheduler for application wide tasks * The singloton class TaskManager is responsible for managing the TaskSchedulers * MessageListeners and Messages hold an optional schedulerId, both must be set to only send to a specific TaskScheduler * Bookmark buttons where split off into a separate view per tab, bookmark managemement is done in the application * History menu processing is done by the QtMainWindow now * Screen search is an application component, the responders are always changed to the active tab * Plugin messages are opened in a new tab * Symbols can be opened in a new tab via middle click/context menu in graph, code, history dropdown * Full text index creation is mutexed now in PersistenStorage to make it fully thread-safe * All tabs are closed when switching projects * Tab contents are only animated when visible fortune cookie message = Catch your lucky star!
